I am looking for extension cable as well, its not easy to find compatible cable online. It would be great if Harvst sell them in their shop, with more flexibility options.
pansy - we don't recommend extending the grow light wires- the lights use quite a lot of power, and extending the cables will make them dimmer. They are designed to be mounted within a metre or so of the control unit for maximum brightness. It is possible though if you really want - let us know and we'll make up a custom cable or two for you.
